The choice of cutting device should be based on what factor?

Choosing a cutting device for diving primarily hinges on the types of hazards that might be encountered during the dive. This is critical because divers often face unique challenges based on the underwater environment, such as entanglements with fishing lines, nets, or other debris. The appropriate cutting tool must be effective in safely addressing these specific situations, ensuring that divers can quickly free themselves or assist others in emergencies.

While factors like current strength or the size of marine creatures can influence dive preparation and safety, they do not directly determine the suitability of a cutting device. Similarly, the size of a wreck may affect dive strategies or entry methods, but it isn’t a determining factor in the choice of cutting tools. In essence, understanding potential hazards and selecting a cutting device that can effectively handle those risks enhances overall safety and emergency readiness during the dive.
